yes they can fire you. but it will be based on your not showing up for work and not doing your job.

that is if you are located in the USA. America has what they call american disabilities act. what that means is employers can not take into consideration a persons mental or physical health.

the short version is employers cant ask if you have a mental illness and when evaluating you'r work they cant use your being absent from work based on mental illness.

all they can do is the same as they do for normal people ..offer sick leave, vacation time that can be used for what ever purposes the employees need time off for. then should something come up unexpected the employers can either offer unpaid leave of absence or fire the employee for not showing up to work.

because of the laws we have in america employers cant even ask an employee if the reason they are not coming in to work is because of a mental illness or in a mental hospital.

doesnt sound fair I know but the handicapped cant have it both ways....have the same rights and standards in the work place as normal people and then not get fired because they are not at work to do their job.

I have noticed though that many work places will "work something out" if the employee knows ahead of time they will be hospitalized and take the time to talk with their supervisors and bosses so that a sub can come in to do the absent employees job so that all the other employees and job areas are not adversely affected by one person just one day for how ever many number of days not show up to do their job.

maybe you can explain to your boss that you need some personal time off, how long you will need, and "work something out"
