Descrimination: A full hot meal or soup and a sandwich

Just when I thought our management couldn't get any more pathetic. Well, they have pushed the envelope even further.
At the begining of December the dietary manager decided (without notice) that the meal times during the day were going to change. Staff were not going to be served a full hot meal until after 12:30 pm, after the residents have all eaten their lunch. However, there are two categories of workers that usually have their lunch earlier which is 10:45 am and 11:15 am. They are the Practical Nurses and the Care Aides. For these workers they will only be entitled to have hot soup and a sandwich.
Well this didn't sit too well with these workers. So they decided on their own to change their lunch times in order for them to have the same full hot meal options that the rest of the workers were having in the building. Well the Director of Nursing got wind of this and she was not impressed. She ordered the Practical Nurses and the Care Aides to go back to their previous meal times and any change in staff meal times must go through proper channels and put to a vote with the union.
I have since filed a descrimination grievance and nothing will be looked into until after the first week of January. However, with this particular union's lousy track record of not wanting to hold the employer accountable on anything, I'm not holding my breath. So for over a month the Practical Nurses and the Care Aides will be served the equivalant of a soup kitchen at lunch time, even though their shift starts the same time as other departments (including the R.N.'s) in the building and will be treated as second class health care workers. This has created enourmous amounts of unnecesary tenstion through out the building.
