ummm my first thought here when reading this thread was....ok who is the boss and who is the employee?

heres why...

its a bosses job to tell the employee what to do and when to do it
its the employees job to do what the boss tells them to do.

an employee doesnt tell a boss what to do. (quickest way to lose a job here in the USA is to try and "boss" the boss) think of it like you have your own home and you hire a maid to come in and clean your home and the maid instead tells you what ..........you ......... should do in your own home... your the boss and the maid is the employee, the maid follows your orders not you following the maids orders kind of thing.

now for the situation...

you completed some work, put it on his desk for his signature. he tells you he will sign them when he gets back from the gym... then its your job to wait for his signature, then distribute what he has signed...

thats your job and his...

question most jobs entail more than just that. most people have other things that they must do.... more paperwork or filing or what ever... so what about instead of just sitting there waiting for signatures, you move on to other work at your desk, that way you wont feel the time is wasted...

example when I had a boss, their schedules never matched up with mine. but there was always files to do, job related phone calls to make, job related errands to do, paperwork paperwork paperwork....

While waiting for my supervisors and bosses to do their part I continued with work of my own. by the time the supervisors and bosses had done their part I was just bringing in another batch of stuff for them to do... we though we had different work hours we got our respective parts of the job completed with out affecting each others abilities to do our own jobs.

my point is since you know this boss is going to go to the gym and then do his part of the job, you can still do your part of the job by moving on to the next thing that you have to do in your job while waiting for him....

all jobs here in the USA are like this where the boss does his own thing and the employees have to follow and do what the bosses tell them to do and when the boss is busy with his day the employees continue their job by having things on their desks that they can do when the boss is busy.

maybe you can set up your workload and work station accordingly so that while he is at the gym you can continue to do your job.
