Until January, I worked PT but offered to work as needed when FT position opened. In rush to fill position it was given to me. Prior to accepting,I informed them that it was temporary and i had vacation coming up, in which I gave a time frame for. Change in work status causes need for days off that weren't earned. Agreed to take time w/o pay.2 weeks notice is required for time off requests, notice given 1 month in advance. Employer states time won't be granted if they can't find staff. I reminded them of temporary employment status and now they want me to resign. I think this is a tactic to avoid firing me and ensure denial of unemployment benefits. How should handle it?
