What types of restraints of trade are unlawful?

Unlawful restraints of trade typically include agreements that excessively limit competition or market access, such as price-fixing, market division, and bid-rigging. Additionally, contracts that impose unreasonable non-compete clauses on employees, preventing them from working in their field for an extended period or within a broad geographic area, can also be deemed unlawful. These restraints are often considered violations of antitrust laws, which aim to promote fair competition and protect consumer interests. Courts generally assess the reasonableness and impact of these restraints on the market.
