what would be a good policy to implement to fix these department issues?

2. There is inconsistency between the two lead workers. One tends to honor all requests, even when it means the floor is short staffed for a shift. The other often appears to "play favorites", routinely giving her friends preference when requests conflict. 3. Some people are allowed to take time without pay when they run out of vacation time while others are refused or even punished. Some staff are even allowed unpaid time off when their areas are backlogged, leaving others to do their work. 4. The same, senior staff people put requests in a full year ahead of time for certain holidays so they ALWAYS get those holidays off while the rest of the staff have to cover more than their share of holiday hours. In general, senior staff members almost always get their choice of vacation days and times. Newer employees are expected to work around them. 5. There is no back-up system when people call in sick so many recent evenings have been staffed with only one person. The part-time people are the first ones called to back-up which means they often go for a month or more without a weekend off. 6. Changes t the schedule, once it is posted, are not communicated so people have missed shifts because they didn't know they had been scheduled on their weekend off
