I am a salaried worker that is required to work 50 hours a week. My salary is $1230 biweekly. On my paycheck stubs it says I am only paid for 40 hours. When I questioned this it was told that all managers of the company are "expected" to work 50 hours and that your pay increases and reviews will be affected by this if your are not working the 50 weekly.
I was not meeting up to their standards and am under my 90 days of employment and was given a written warning and put on a 6 month probation.
My question is, is this legal? Can they hold back increases and hold you accountable for 50 hours but only pay you for 40?

By salaried, do you need salaried exempt? If you are an exempt employee you get paid a fixed weekly salary no matter how many hrs. you work. Your employer can require you to work 50 hrs. a week - your paycheck may just show 40 hrs. for accounting purposes. You don't get paid overtime over 40 hrs. if you are exempt.

If you are not working the 50 hrs. as required, they can hold back salary increases & put you on probation as a disciplinary action.

It seems from your post you are talking exempt & not non-exempt. A non-exempt employee has to work the # of hrs. required but has to be paid overtime after 40 hrs. a week.

FYI, many payroll softwares automatically put 40 hours on a paystub for exempt employees. It does not mean that you are only getting paid for 40 hours.
