Pros
Marcus has managed to employ many great, dedicated and hardworking people from the stewards to management, many, if not all of the hotel level employees take great pride in the job they do and are fun, energetic, enjoyable people to surround yourself with on a daily basis. Marcus is an operations company, and if you're interested in developing in Hotel Operations, you can find yourself on a path pretty easily here, particularly if you're open to relocation. In Milwaukee in particular, the Marcus name is respected and a city institution.
Cons
Marcus is an operations company, and that's great if you're interested in hotel operations. If you're not, there is no real opportunity for growth of development. Restaurant management, HR, Marketing, Sales - you can find a position in these areas, but will likely see no true interest in developing a career path from your superiors. Furthermore, if you're interested in your own professional growth, you're on your own. The unspoken mantra here is "if you don't like it, you can leave it." And there's not much desire to retain talent - despite the obvious benefits of retaining young talent and developing it. Work/life balance for anyone at the management level is difficult as well. Every department is understaffed and over-demanded. It's expected in the hospitality industry that work/life balance won't be perfect, but a great company would make the effort to make work more welcoming.
